A basic search using the YP API.

  results = client.search(searchloc: 93551, term: 'pizza', listingcount: 1, sort: 'distance')

  puts results

yp.rb

# YP back-end code for making the API calls

require "yp/version"

require "faraday_middleware"
require "json"

module Yp

    SEARCH_PATH = "listings/v1/search"
    DETAILS_PATH = "listings/v1/details"

    def initialize(options={})
      @api_key = options[:api_key]
    end

    # e.g. client.search(searchloc: "94109", term: "kayak")
    # http://api2.yp.com/listings/v1/search
    def search(options={})
      response = connection.get do |req|
        req.url SEARCH_PATH, options
      end

      JSON.parse(response.body)['searchResult']['searchListings']['searchListing']
    end

    # e.g. client.details("30624356")
    # http://api2.yp.com/listings/v1/details?listingid=30624356&key=xxxxxxxxxx
    def details(listingid)
      response = connection.get do |req|
        req.url DETAILS_PATH, {listingid: listingid}
      end

      JSON.parse(response.body)['listingsDetailsResult']['listingsDetails']['listingDetail'][0]
    end

    private

    def connection
      params = {}
      params[:key] = @api_key if @api_key
      params[:format] = "json"

      conn = Faraday.new(url: "#{API_URL}", params: params) do |builder|
        builder.use Faraday::Request::UrlEncoded  # convert request params as "www-form-urlencoded"
        builder.use Faraday::Adapter::NetHttp     # make http requests with Net::HTTP
      end
    end


  end
end

I put the above code in, but now I get the "Sinatra doesn't know this ditty". Updated code is below.

require 'rubygems'
require 'sinatra'
require 'yp'

# index.rb 

post '/' do
  halt 400 unless params[:location]
  halt 400 unless params[:term]

  client = Yp::Client.new(api_key: "e89cba4b974a122e408d1723626f3709")
  @results = client.search(searchloc: params[:location], term: params[:term], listingcount: 1, sort: 'distance')

  erb :index
end
